"ALL OF YOU! DIE WITH ME!" the Fire Lord Roared as the keys began shuddering.
He was using the keys, to blow up the keys themselves.
The Wind King picked up on the stunt instantly and rushed forward, he wasn't letting him get away with this. So, although bloodied, wounded, and incredibly exhausted he still rushed forward.
He already dropped a couple of cultivation levels from the earlier fight and was in no condition to continue on, but he still moved with the pride of kings, risking his life for the safety of others.
I shouldn't be able to help, the moment I move anywhere near the Fire Lord I'd melt, but I couldn't just die… the moment the Fire Lord succeeds in blowing up the Keys, we're all dead, this is nuclear level damage only if the nuke is the size of a planet, and there are five of them.
